Everything I've seen about it so far tells me that it will be, unless you're one of those tiny percentage of players who can solo anything.

Logically things look to be close to existing. You will still have the current adept chasing (T5) in weapons and armor requiring raids or max difficulty content. What you gain over standard drops (T3, T4) seem to be be minimal. You still have explore modes and various levels of difficulty. Just lots more complexity. The question is where in the scale of fixes and new bugs will this change bring? Paid for it hoping not to be disappointed.
